Abstract
Parthenogenetic haploid embryos of 'Crimson Sweet', 'Halep Karasil, 'S ugar Baby' and 'Panonia F1' watermelon [Citrullus lanatus (Thunb.) Mat sum. & Nakai] were obtained after pollination with gamma-irradiated (2 00 or 300 Gy) pollen. Some globular and heart-shaped embryos were obse rved in fruit harvested 2 to 5 weeks after pollination. The number of embryos per 100 seeds was highest for 'Halep Karasi'. After in vitro c ulture, 17 haploid plants were obtained and doubled haploid lines were generated after chromosome doubling using colchicine.
